Generate Combinations Of Elements Of A List<T> In .NET 4.0?
Jul 13, 2009I would like a function generate all of the k-combinations of elements from a List of n elements. Note that I am looking for combinations, not permutations, and that we need a solution for varying k (i.e., hard-coding the loops is a no-no).
I am looking for a solution that is a) elegant, and b) can be coded in VB10/.Net 4.0.
This means a) solutions requiring LINQ are ok, b) those using the C# "yield" command are not.
The order of the combinations is not important (i.e., lexicographical, Gray-code, what-have-you) and elegance is favored over performance, if the two are in conflict.
(The OCaml and C# solutions here would be perfect, if they could be coded in VB10.)
.net - Generate All Unique Combinations Of Elements Of A IEnumerable(Of T)?
May 12, 2011This question is virtually the same as this SO post, only I'm looking for a VB.NET (.NET 4) solution. I've spun my wheels long enough trying to come up with a generic solution to solving this "power set" problem.
Dim choices As IEnumerable(Of String) = {"Coffee", "Tea", "Milk", "Cookies"}
Dim choiceSets = choices.CombineAll()
I'm looking for choiceSets to be an IEnumerable(Of IEnumerable(Of T)) so that I can do something like:
For each choiceSet in choiceSets
Console.WriteLine(String.Join(", ", choiceSet))
Next
[code]...
As you can see, this is every non-repeating combination from the source IEnumerable(Of T) (which could have 1 to many items in it - this example only had 4), it operates based on the order of the items in the source IEnumerable(Of T), and each item in the list is >= the previous item in terms of number of items in the inner IEnumerable(Of T).
For what it's worth, this is not homework; though it sure does feel like it. EDIT: Updated the example so it does not look like the result is alphabetically sorted, to stress that the source IEnumerable(Of T)'s existing order is used and added a 4th choice to clarify the sorting requirement within each set.
How To Generate All Real Combinations From String Array
Apr 2, 2012I need to generate all combinations (not permutations) in VB .NET, I've been search and all I found is for permutations (some says combinations but when I was try it, all are permutations).
What I need is to generate combinations from string array:
Dim data_array As String() = {"one", "two", "three", "four", "five", "six"}
I need that: If I say just 1 length, it must returns:
one
two
three
four
five
six
If I say 2 length, it must returns:
oneone
onetwo
onethree
onefour
... etc ...
twoone
twotwo
twothree
... etc ...
And continues til end with all combinations. If I say more length do it as well.
Itextsharp: What Is The Height Of A Regular PDF Page In Pixels
Dec 15, 2009what is the height of a regular PDF page in pixels?
i heard it was something like this:
Dim pgSize As New iTextSharp.text.Rectangle(595, 792)
but i am adding an image that takes up maybe half the height, and even though pgSize looks like a full page and the image takes up only half of it, i am getting a height of like 619 for the image? i do not know if it is in the same units?
Pixel Counter - Count The Black Pixels The Grey Pixels The More Grey Pixels
Jul 27, 2009I'm trying to make a -what i thought would be simple app.My intention was to build program that:1) i'd provide a grayscale image2) the program would count the black pixels the grey pixels the more grey pixels etc. (the hue) and the white3) would make the percentage sum of all pixels, that is: 300.000 black pixels (rgb 0 0 0) etc. given that 0 is the black, 100 the white. e.g a simple grayscale image is 55.2 white
This was my way and i don't think that is useful:
First of a button to convert the image to greyscale:
Dim bm as new Bitmap(source.Width,source.Height)
Dim x
Dim y
[CODE]...
Secondly, -and that's the stupid way- i did -or better i wanted to do- this: i put the code to dynamically create labels, each label having the colour of a pixel as background colour and as text the colour converted to rgb
The third step which i intended to do (i couldn't get pas two) was to sum up the labels etc.

Combinations Of 16 Take By 2 Using LINQ

Permutations Or Combinations ?
Dec 28, 2010I think what I'm trying to do is considered a permutation but I could be wrong. I've come across several examples of how to permutate a string as follows:
Permutations of {A B C}: {A B C}, {A C B}, {B A C}, {B C A}, {C A B}, {C B A}
What I'm needing are results similar to this (using the same input) with a repeat of each item to create a list of all possible combinations: {A A A}, {A A B}, {A A C}, {A B A}, {A B B}, {A B C}, {A C A}, {A C B}, {A C C}...and so on.
Below is some code that I found that almost gets me there with an exception of the repeated values:
'Generates all possible combinations from a series of words
Public Function PermutateString(ByVal input_string As List(Of String), Optional ByVal Base As String = "") As List(Of String)

View 3 RepliesGenerating A List From Combinations?
Aug 3, 2009I am writing an application in which we have a Product Module, Now instead of defining individual products, we want to just state the Size Ranges in Width, height and different size scale available, and then automatically generate a list of products with all the Size combinations. I cant figure how to do this.Ill give an example.This is how we define a product
Product[code].....
If i had a fixed number of Size types i would just run For loops within for loops and inside the inner most for loop write an Add Item statement with Index of evry selected item, however since the Size types are dynamic, i need to write a recursive loop, and i just cant figure how to.

Achieve A List With All Possible Combinations Of Letters?
Sep 9, 2009I was wondering how to achieve a list with all possible combinations of letters. Now there are some nice examples on the Internet, however, I'd like to have the following:
Let's assume you have 3 letters (A, B, C), and have a limit length of 3, then it should display this list:
A
B
C
AA
[Code].....
Now, this would be fine with recursive calls I think, but I find it really difficult to think how to code that and how the computer will execute the code. It would be easier if all possibilities had a length of 3, but here that isn't the case.

Get Different Combinations Depending On Checked CheckBoxes
Jan 15, 2012Example: That's 8 different combinations:
1, X, 1
1, X, X
1, 2, 1
1, 2, X
X, X, 1
X, X, X
X, X, 1
X, 2, X
Any way to get the different combinations depending on the Checked checkboxes into an ArrayList. One entry per possible combination (like the example above). Note this example is just for 3 games, I will have 13 games in my program so if you click all checkboxes thats 1,6M combinations. Is it really wise to have 1,6M entries in an Array? I also want to be able to set demands, like: delete all lines in the Array containing two X. Maybe an ArrayList isn't the way to go?

Math - Produce All The Possible Combinations Of Numbers
Oct 6, 2009I have 36 numbers in sets of 5. (eg. 1-2-3-4-5, 2-3-4-5-6 etc..) I need to find all the possible combinations of these numbers which total the same sum. For instance the lowest sum would be: 1 + 2 + 3 + 4 + 5 = 15. The highest possible sum is: 32 + 33 + 34 + 35 + 36 = 170. Now every five number combination within these 36 numbers will sum up between 15 and 170. How would I go about this in vb.net to produce all the possible combinations which would total say 92.
